The our fciuclt is oyclissry cousizruci ioo. and nasal not he described. specificslly.

Resting on the encl sili of car truck, sncl projecting heyonci she ssme are s pair of suhsisncislly parallel supporting Tours 2, wiich are preferablyprovided with e1 ;eu-- sions 3 which engage the uncle siclc of the irsnsom i of the truck. The bass 2 are preferably arranged on the outsiiie of shs Whesl guards 5 of the truck and secured; izlisreto by means of bolts 6. Of course, tho bars 9, may be secured to the truck in any oth preferred manner. The bars 2 are 'ei oiiei'zihly secured to the end siil h clsmpiu members or clips 7. in prsctice I profs; co utilize bolts 8 of she broke springs for securing the clamping; memosi's 7 ivhe eml siil, as this obviates the necessity of drilling och the boss 2, sml their braces, sire only parts of the smppoi O mechanism which are secured. to the can mick, snc'i. that the tschment of these members in HIG EiSZE injures the truck.

Sliclsbly mounted on each of the bars are two stirrups 13 and H, esch of which is preferably substantially U'shspeci Pivotzzlly connected to the ssh-cups 14; by pins 15 is :1v sling 16, and pivotally suspended from the stirrups 18 is a sling 1'? The slingfslG and 17 are preferably of the same size and formed of cylindrical reels, although of course I do not limit myself so this con- StlflciSiOH. The slings ore each substantially iJ-shspcol arcs-constructed clepencL ing sncljmembers'oi iiillES pivoted. to chestirrups and with cross-liars composting; lower portions of each psi of links and cross-bars are integral. It is apparent,

' however, that the links and cross-bars need not be integral and that the parts may as.

. held in spaced relation, and an equal disbolted or otherwise secured to the down tance. apart, by spacing bars 13 which are connected thereto by the pins 15 which support the slings 16 and 17. Each of the spacing bars 18 has a screw threaded extension19,,which passes through a guide 20 ward extension 11 of one of the suspension bars 2. Each of the screw-threaded extensions19 carries nuts 22 and 23', arranged on opposite sides of the guide 20. By adjusting the nuts 22 and 23, the stirrups on either of the bars 2 maybe adjustedlongitudinally thereon, thereby moving the members or slings-16 and 17 laterally. The purpose of this adjustment will be hereinafter set forth.

Secured to the. opposite sides of the sling 16, by suitable clamping members 2 (Fig. 4), are tension rods 25. Each of the rods 25 passes through the extremity 12 of one of the bars 2, and is provided at its end with a screw-threaded portion onto which is threaded a tension nut 26. Surrounding each of the rods 25, and interposed between the tension nuts26 and spring seats 27, which bear against the portions 12 of the bars 2, are tension springs-28.

The generator, or other dynamo electric machine, 30, which may be of any preferred type, is adapted to be supported by the U- shaped slings 16 and 17 in a manner which I shall now describe.

In the device illustrated, the generator 'is suitably secured to abed plate 31, which is provided at opposite sides with the bear ing portions 32, (Figs. 3 and 6), for receiving the cross-bars of the. slings 16 and 17. The bearing portions 32 are provided with caps 33, secured in place by bolts 34. The bed plate thus serves to hold the crossbars in spaced and parallelrelation. While the bed plate;is securely fixed to the slings 16 and 17 by the caps 33, yet it is free to slide longitudinallyof the cross bars and the cross-bars are free to turn in the bearing portions 32. The generator should be so mounted on the bed plate that the armature shaft is substantially parallel to the crossbars of the slings 1(5 and 17.

While I have shown the generator mounted on a bed plate, it should be. understood that the generator casing might be directly secured to the slings, or might have a bed plateformed integrally therewith or might be supported in various other ways.

The armature shaft of the generator carries a pulley 35 adapted to be driven from a pulley 36 on the car axle by means of a belt 37.

menace To adjust the generator to bring its armature shaft into parallel relation with the car axle, it is only necessary to shift one or both ends, of the slings 16 and 17 laterally, in the manner previously set forth. The desired slack ofthe belt can also be obtained in the same manner, that is, by adjusting the nuts 22 and 23. To render the pulley on the armature shaft in alinement with the pulley on the car axle, it is only necessary to slide the generator longitudinally of the cross-bars. To prevent longitudinal movement of the generator; after proper adjustment, I provide on the cross-bars stops 38, arranged on opposite side of the bed plate and adapted to be clamped to the cross-bars. The stops are formed in two parts secured together by bolts 39. To regulate the tension on the belt, it is only necessary to ad just the tension nuts.

Inasmuch as the slings 16 and 17 are of the same size andare held in the same spaced relation, both at the top and bottom, a parallel motion is produced whereby, when the links swing back and forth, thegenen ator always remains horizontal, its armature shaft always parallel to the car axle and its pulley always in alinement with the pulley on the car axle. It is apparent that the generator is supported on or in a swinging cradle, carriage'or frame. With this arrangement the generator is always easily accessible and may be readily removed from its supporting slings by removing the-caps 33. It may also be as easily replaced.

The accessibility of the generator is due to a great extent to the fact that I eliminate the cross bar connectin the outer ends of the supporting bars, which is usually found in suspensions of this general character and which of necessity impedes access to the generator. (In a co-pending application, Ser. No. 5 5,267, filed June'6, 1910, I have described and" claimed a somewhat similar generator suspension applied to a steel car truck.

I do not desire to limit myself to the form of device described above nor to the details thereof, as it is apparent that this formv was selected for the purpose of illustration only. I desire therefore to include any suitable equivalent means for accomplishing the de sired results and falling within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
